SAFETY-RAZOR.

Patented Dec. 9,1913.

To all whom zit may concern.'

Be it known that T, MATTHEW C. SHARP- Niion, a citizen of the United States,.resid ingat Cornville, in the county of Yavapai and State of Arizona, have invented new and useful Tmprovements in Safety-Razors, of which the following is a specification.

This invention relates to safety razors and it is the object of the invention to provide means whereby the blade of the razor may be simply and conveniently shifted laterally across the ard, whereby a shearing cut may be obtained.

Further objects of the invention will appear asthe follow' g specific description is read in connectiednwithA the accompanying drawing, which forms a part of this application, and in which Figure 1 is a perspective View of the device. Fig. 2 is a side elevation with a portion of the casing removed. Fig. 3 is a detailed 4vertical sectional view. Fig. 4 is a top plan view with a part .of the blade broken away. Fig. 5 is a perspective view of the blade used looking from the under side. Fig. 6 is a detail longitudinal section showing a. modification of the driving mechanism.

Referring more particularly to the drawing, ll represents a substantially semi-cylindrical casing to which is secured an operating or manipulating handle 2 preferably formedfwith a longltudinal channel 3 and which extendsv diagonally from the casing. Mounted within the casing is a frame l upon which is mounted a train of gears 5 includin a sprin drum 6 which drives the same. ncluded 1n the train is a suitable escapement mechanism 7 which controls the speed of movement and projecting from the bottom of the casing is the winding shaft of the spring drum by. which the tension of the spring therein may be increased when desired. This winding shaft has secured there- 'on the usual turn button 8.

at will hereinafter be termed the secondary shaft of the train is indicated at 9 and-is journaled in the frame 4 having its upper end projecting through the casing and provided wgith a Wrist pin 10 carried upon 4themouterend of a crank arm 11. This wrist pin is adapted to engagein a slot 12 formed in a substantially U-shaped shuttle 13 in 'which is detachably held the razor blade 111.

This blade is mounted upon the top of the casing and is adapted to reciprocate thereover, being held in operative position by a strap 15 which lies over the blade adjacent -rent .is led into the motor by the circuit wires 21 which pass through the handle 2. The casing in each form is providedl with a door 22 by which the mechanism therein maybe covered andpso that access may be had thereto when repairs are needed or for any other suitable purpose. In the structure shown in Fig. 6 a suitable switch is preferably mounted upon the handle so as to control the current to the motor.

In the operation of the device the guard and razor are pulled over the face at an acute angle thereto and with a straight pull, the motor being turned on so as to reciprocate the blade at the proper speed. This reciprocation of the blade across the teeth formed by the slots in the guard acts in a similar manner to .the ordinary cutter bar on a reaper or mowing machine and as the edge 0f the blade is straight a sawing action is produced which readily severs the whiskers from the face.

Having thus described the invention, what stantiallyA U-shaped shuttle detaehably emln testimony whereof I aiiix my signature bracing one edge of the blade and reciproin presence of two Witnesses.
